FLUID-PRESSURE REGULATOR.

To all whom it may concern:

Be it known that I, MAX JAsrERsuN, a subject of the German Emperor,residing at Hamburg, Germany, have invented a certain new and usefulImprovement in Fluid- Pressure Regulators, of which the following is aspecification.

This invention relates to imprmf'ements in devices for regulating thepressure of gases, especially of coal gas heating and power gas in whichthe extent of opening' or closing of the valves is regulated by therising and falling of a diaphragm or cup which is under the influence ofthe gas and therefore decreases or increases the gas supply accordingly.I The gas which is conducted from the supply pipe to a valve casingtlows from this through an upper and lower valve in quantitiescorrespoiiding to the consumption, into the upper part of the regulatorconnected with the diaphragm chamber and thence into the conduit pipeleading to the place of consumption. Such devices are already known;they have however, not given satisfactory results owing to the injuriousinfluence on the valves by the current of gas and the precipitationfater from the gas as well as owing to the friction of the valvespindle.

The present invention overcomes these objections by providing meanswhich protects the valves from the effect of the direct current of gas;and by so constructing` and arranging the valves that the are removedfrom the path of the water of condensation, lwhich flows in from moreelevated positions. The friction created by the movement of the valvespindle is also obviated by suspending the valve carrying spindle fromthe diaphragm and thereby doing away with all guides and close fittingbearings for the said spindle. Tt will be apparent therefore, that onlythe static gas pressure and the regulating diaphragm can act upon thevalve, so that all unfavorable influences are done away with. Among thecurrents of gas which should not be permitted to act directly upon thediaphragm are .not only that pressure or current which comes into thepassage owing to consumption of gas but also that current which arisesthrough the current of gas strealning from the valve with the force ofthe difference of pressure and concentrating toward the valve rod in anarrow current. This current is very unfavorable for operatingl on thediaphragm Speccaton of Letters Patent.

and therefore in the present invention, devices are arranged whichprevent a direct flow of the gas from the valves, into the diaphragmchamber, or lnake the working of the penetrating gas currentineffectual.

further injurious influence of the valve can take place if condensedwater collects in conduits situated higher up, and reaches the valve. Toprevent this, the present invention provides a receptacle in which theprecipitation 'ater is caught. rlhis receptacle can be placed in frontof the regulator or within it. In the latter case, it can be arranged infront of or under the valve. The precipitation water, flows away intothis receptacle without touching the valve. At the bottom of thisreceptacle there is an outlet channel which is protected against thepenetration of the unregulated gas by a plug of wadding or the like, orby a flap valve.

Further objects and advantages will be apparent from the followingdescription with reference to the accompanying drawing. wherein,

.Figure l is a view in vertical section of a pipe main embodying thepresent invention; Fig. 2 is a view in vertical section on the line A--Bof Fig. 1; Fig. 3 is a view in vertical section on the line C-D of Fig.l; and Fig. el. is a detail view of a modified form of the meansdisclosed in Figs. l and 2, for preventing the direct current of gasfrom enteringI the diaphragm chamber.

Referring more specifically to the drawings and particularly to Fig. 1,the apparatus consists of a casing l, divided into upper and lowersections as indicated by the reference characters lb and la,respectively which are connected to the gas outlet and inlet pipes.

l/Vithin the lower section of the casing la, a hollow body 2, openabove, is arranged, the distance between the front and rear wallsthereof being less than the distance bet veen the side walls, so thatbetween the front and rear walls of the hollow body or receptacle 2, andthe corresponding walls of the casing, there is a hollow space to permitthe passage of the unregulated gas. The hollow body 2 is provided at thefront part of its base with a projection 3, which serves, on the onehand to form a hollow space between the base of the hollow body andcasing for the admittance of gas, and on the other hand to divert thecurrent of gas.

Through the bottom of the hollow body a passageway 4 is formed which isclosed by means of a iiap valve 5, this valve normally closing thepassageway 4, until the water, collected in receptacle 2, reaches apredetermined point, that is until the pressure of the water' againstthe inner face of the valve 5 overcomes the strength of the valve andthe gas pressure on the outer face thereof.

Above the hollow body 2 and in abutment therewith, as will be explainedhereafter, a circular partition 6 is arranged, which has, ondiametrically opposite sides, a pair of slots 7 which are incommunication with the passages formed for the unregulated gases betweenthe front and rear walls of the body 2, and the lower section of thecasing 1, while on the other two diametrically opposite sides, slots 8are formed which establish communication between the space within thehollow body 2 and the upper section 1b of the casing 1. Above thepartition 6, there is arranged a member 9 terminating in an inwardlyextending flange which forms a valve seat for the conical valve 14. Asis, of course, understood, the partition 6 is hollow so as to receivethe valve stem and valves and permit. movement thereof. The inner faceof this partition is formed with valve seats 11, 12 and 13 to receivethe valves 14, 15 and 16 respectively.

The valves 14 and 16 which are secured to the valve rod 19 aredifferently formed, for example the valve 14 is formed as a conicalvalve and valve 16 as a disk valve, whereby when the valve sinks thepressure on the lower valve is greater, because with the upper conicalvalve the only pressure resisting surface to be taken into considerationis the conical section perpendicular to the axis always at that pointwhere the perpendicular line drawn from the valve seat to the valve conestrikes the latter. By this means a very sensitive deflection of thevalve is attained when the gas consumption gets greater. On the valverod 19 between valves 14 and 16, another disk valve 15 is fixed which,on the diaphragm tearing almost stops up the seat 12. This valve alsopromotes the distribution of the unregulated gas current entering thebody of the valve. The valves are I mounted on a common valve spindle19, which is provided with joints 20 and 21. Both slots 7, heretoforementioned, of the partition 6 serve to admit the gas from the inletpipe, so that it can pass upwardly through the valves 14 into the upperpart of the casing or downward through the valve 16 into the hollow body2. The hollow body 2 is pressed against the partition 6 by means of ascrew bolt 17 inclosed in a cap 18. Both slots 8 of' the partition 6 aresituated above and in communication with the interior space of thehollow body 2, so that the gas can escape upward through the same. The

@have top of the upper half of the frame 1b is fitted with a dependingtubular prolongation 22, having a bore 23 through which the valvespindle 19 is inserted in a pendulum like manner. The outer edge of thediaphragm is pulled over the upwardly projecting circular rim 24. In themiddle of the diaphragm the valve spindle 19 is secured by means of nuts26 and 27. A protecting cover 28 is placed over the diaphragm. The upperportion of the valve 14 has an upwardly extending flange 30 which formsan annular space 34. 1n the latter lies a wick 35 which is conducted tothe outside through a bore in the valve. This wick carries any glycerinwhich may have dropped from the diaphragm, out of the ring space.

As heretofore stated, it is desirable that the diaphragm be protected asmuch as possible from the energy of the flowing gas, so thatsubstantially only the static pressure of the gas will act thereon. Thediaphragm may be protected in various ways, as for example, by thedepending prolongation 22 of the casing 1b, which extends into theannular space 34 in the valve 14, see F ig. 1, and which prevents thedirect current of gas from entering into the diaphragm chamber throughthe bore 23. The same result can be obtained by means of an annularprojection 31, formed on the valve rod spindle 19 directly below theopening or bore 23, as shown in Fig. 4.

The operation of the device is as follows :"-The gas flows into theinner valve space of the partition 6 through the inlet pipe withunregulated pressure. Should no consumption ofl gas take place, thepressure above and below the valves 14 and 16 is the same, the diaphragmis pressed up by the increased gas pressure within the diaphragm chamberand the valves 14 and 16 are closed. As soon as any consumption of gastakes place, the pressure existing in the diaphragm chamber falls andthus permits the lowering of the diaphragm together with the valves 14and 16, which are connected to the diaphragm. lVhen the consumption ofthe gas diminishes the pressure on the diaphragm is increased, wherebythe valves are proportionately raised. Should the diaphragm become leakyor broken the valve spindle falls whereby the valve 14 falls into itsseat and closes, and the valve 15 leaves only a small space between thevalve and its seat 12, so that the amount of gas passing into the outletpipe and thence to the lighting system, will be materially decreased,thus giving indication that the diaphragm for some reason is not in goodworking order. The condensation water, if' there be any, flows awaythrough the slots S of the partition 6 into the hollow body 2 and thenceto the gas-meter. Should very much precipitation water come suddenly sothat the inflow is greater' than the outflow, which can only occur underspecially unfavorable circumstances, the water will rise in the hollowbody 2 till. the valve 16 is finally immersed and in consequence of theloss of weight, will be pushed up higher. Also in this case thedisarrangement is shown by the lights burning lower. The regulatortherefore indicates automatically every irregularity without occasioninga complete shutting oli' of gas, which might cause an accident.
